1 Application filedqctober '27, '1920. Serial No; 419,856 7 This invention relates: to more particularly to firexpots and has for itsprimary object to improve upon vthe structure of fire pots as; shown in: Letters Patent No. 1,279A19' issuedxto. me September 17, 1918.

p of theinvention istoprovide an improved fire pot tobeused in conjunction with. a :boiler structure disclosed in said Letters ner. to permit the circulation of water through the fire pot whereby heat will be absorbed from the burning 'fuel'in a manner Another obj ect:

A further object of the invention is to generally improve upon furnaces and fire pots therefor 1 by providing an improved be simple, yet efficient at a comparatively low cost. 7 In order that those skilled have a full UIJdGI'StELIIdlDg of the invention,

I have illustrated a desirable andpreferred embodiment of. the same in the accompanying drawing forming a part of th s specifi cation,

in which like reference: characters refer to the same parts,- 1 I In the drawing:- 1 y '1 Figure 1 is a side elevation of the fire pot showing'the boiler construction fragmentarily. i

The fire pot about to be described maybe used with"a'boiler'construction of conventional form but is especially" adapted to be used with a boiler structure such as is illustrated in Letters the legs 10 circumthe casing of the furnace and suitably spaced from each other. The prefered form of the present 1' fire pot consists of a plurality of parallel furnaces l and 3 extending in thesame legs?

Q'Thei superimposed "hollow first from; the 1 bottom: ring theipipes 14:leading into the 8 15: shown particularly in Figure' '4 "of the drawing is provided with open'ings16 upon its'upper and lower side and also with the temp rnunnnn, or enmacmny, NEW Yong, Assiornon; ro ne BoI JEiz QRK, A CORPORATION or rm YORK.

The second from the bottom ring 21 as I and is also provided with dia- I metrically opposed elbows '23 which are p i ea" andf the ring immediately below namely I 1 its bottom be 1 portion for e additional elbow :31 which are suitably communicated with the pipes 32. It will, of course, stood that any in the fire pot. 'Theheat of the burning fuel in the fire pot is the various rings thereby causing fcircula-- therein,

into the boilerstructure and it will be seen that the greate'r portion of the heatis ab-c stracted from thegasesof combustion before they can effect an exit'from the furnace I 'with'the hollow 'rintgs before passing upwardly to i'escape It will be obvious that the legs" lOjthrou gh suitable grate may be placed transmitted through where by therwater will be CllfGlllZLtBd. upwardly structure and that the greater portionthere- V, of will come into contact of various constructions and I have merely elbows 7 hi heommunicate with theil I Theope i s 2 described same in connection with the boiler construction shown in Letters Patent 1,279,419 for convenience. Other usages and advantages of this fire pot will readily occur to those skilled in the art to which this invention appertains.

Obviously, the invention is not limited and restricted to the precise, and exact details of construction as illustrated and described, because it is susceptible of a variety of embodiments, .and many minor mechanical changes may be made in such preferred incorporation of the invention Without departing from the substance or essence of the invention and without the sacrifice of any of its substantial benefits and advantages.

Having thus fully described my invention what I claim as new and desire .to secure by Letters Patent is In combination with ,a boiler, a fire pot comprising a plurality of superimposed hollow rings disposed in parallel relation with each other, the lowermost ring" having water inlets, each ring provided with openings, nipples connecting openings of each ring with openings of the next ring above the same, elbows disposed in pairs on each ring so as to be diametrically disposed from each other and means for communicating the elbows with the boiler.

In testimony whereof I aflix my signature.
